What does the expected value of a binomial distribution with n trials tell you?
1 answer:
Answer:
The expected value of a binomial distribution with n trials tell us about the the average number of successes
Step-by-step explanation:
A binomial distribution is a frequency distribution of the possible number of successful outcomes in a given number of trials such that there is the same probability of success of each of the outcome.
For n trials with probability of success of each outcome as p, expected value of a binomial distribution is given by .
If we toss 200 coins, and X is the number of heads, the expected value of X is 100= (1/2)200.
So, basically the expected value of a binomial distribution with n trials tell us about the the average number of successes .

Explanation:
When u try to find the lengths of a right triangle you use the formula c = √(a² + b²). When you use the formula you take your TWO smallest numbers which is 12.5 and 30 you would plug it in the formula and solve and when you solve you should get 32.5. I checked my answer on a calculator to make sure it was right so js look at the picture below : )
